Bring it all with you.
If you routinely find your zipper straining as you try to close your commuting bag ? even after jettisoning the spare tube and peanut butter sandwich ? it might be time to invest in something bigger. Timbuk2''s Especial Cuatro bag will fit everything you could possibly need, and a few extras that you may or may not.
Featuring many of the same goodies as its younger brother, the Tres, the Cuatro expands to a generous capacity of 3,051 cubic inches while utilizing compression straps with mesh for load management and ventilation. The front flap''s magnetic closure makes accessing your phone or mid-ride nutrition from the saddle easy, and the bag''s Cordura nylon fabric and waterproof liner can withstand its fair share of road grit and inclement weather as you get where you''re going.
